_________________General Description
The MAX4214/MAX4215/MAX4217/MAX4219/MAX4222
are precision, closed-loop, gain of +2 (or -1) buffers
featuring high slew rates, high output current drive, and
low differential gain and phase error. They operate with
a single +3.15V to +11V supply or with 1.575V to 5.5V
dual supplies. The input common-mode voltage range
extends 100mV beyond the negative power-supply rail,
and the output swings Rail-to-Rail
.
These devices require only 5.5mA of quiescent supply
current while achieving a 230MHz -3dB bandwidth and
a 600V/s slew rate. In addition, the MAX4215/
MAX4219 have a disable feature that reduces the sup-
ply current to 400A per buffer. Input voltage noise is
only 10nV/
Hz, and input current noise is only
1.3pA/
Hz. This buffer family is ideal for low-power/low-
voltage applications requiring wide bandwidth, such as
video, communications, and instrumentation systems.
For space-sensitive applications, the MAX4214 comes
in a miniature 5-pin SOT23 package.
